Specification of Letters Patent.

.rammed oct. 5, 1909.

Application filed September 28, i905. Serial Iloftllhret.

which the following is a description.

My invention belongs to the general .class ol devices designed to thoroughly eonnningle air and a suitable liquid, such for example as a hydro-carbon, for any desired purpose, and has :for its object the production of simple end ellicient means I'fior the purpose,

perfectly accomplish the object sought. e

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.

or corresponding arts, Figure l is an elevation of the preerred form of my invention. Fig. 2 is a bottom plan of the same. Fig. tral vertical section of the same. Fig. 4 is a bottom plan of the shell with valve mechanism removed. Fig. 5 is a bottom plan similar to F ig. 2, with the air and liquid valves disconnected and adapted for independent operation. Fig. 6 is a plan View' of the bottom closure of the shell removed from :it-s seat. Fig. 7 is a bottom plan View Fig.y 8 is a plan view of one of the preferred forms of mixing plates, and Figs. 9 and 10 are fragmentary secmodifications of the construction and arrangement of the parts frmingthe lower part of the device.

In the preferred form shown in the drawings, 1 represents the base and 2 a suitable top fora shell or casingi'orining a mixing chamber. The two may he suitably secured together in any preferred manner. As shown the parts are provided with registering lugs, 3 and 4 connected by bolts The base is formed with a preferably circular opening 6, for the reception of a similarly slightly smaller than the opening and which when in place, is spaced therefrom on p annular inlet 8 for the entrance of the liquid also annular which serves asY an provided with lan flange .10 constructed inclesing an opening 9, inlet :for the air, and is outwardly extending 3 1s av cenall sides forming "an to he snugly seated in a corresponding recess or depression l1 formed in the base. Any suitable means may be employed to secure the part 7 in place. 'As shown screws l2`12, serve this purpose.

' The hase is preferably formed with an ois'et part 13 providing ayalve seat 14 `and a supportfor the rotatable liquid valve 15 whpse stem or extension 13 and beneath a pin` 18 or equivalent part on the stein serves to resiliently hold the valve to its seat. A duct 19 serves to conduct the liquid from the supply pipe 20 to the valve 15 which is provided -With a groove 21 formed in its face which closing against the valve seat forms a duct for the liquid. The greci/'13.21 is peculiarly formed it being slightly eccentric to the In the drawings wherein like referencev characters indicate like valve stem and rradually and regularly increased in size rom one end 'to the other, and for convenience may he termed an increasing s irai groove. (Fg. 7.) A duct 22 forme in Athe valve seat and extending from a point in the path of' the groove 21 tothe annular inlet 8' serves to'conduct the liquid to the shell. It -willA thus be seen that when the valve is closed the flat faceof the same covers and ,elfectually closes the .end of the duct 19. As the valve is rotated the duct 19- s first opened by the edge ofthe groove 21 slightly passing thelsame permitting but a small quantity of liquid to enter the groove which conducts it to the duct 22 by which it is nally directed to the annular inlet 8 and is regularly delivered into the shell thereby in a ring' encircling the air. in-

letv 9, for a ipurpose hereafter described.

Further rotation of the valve serves to uncover the end` of the duct by degrees and finally to bring the larger and deeper part ofthe groove into registry therewith thus opening Vthe valve to its maximum capacity. lt Will be seen that by this construction a ver f eticient 'valve is provided by means ot which perfect control of the .delivery of the liquid to the mixing-chamber is effected.

ln the preferred forni a valve of any suitable construction is employed to control the admission of air through the inlet 9. As shown a shutter valve 23, serves this purpose'. lt isdesira-hle that the proportions of liquid and v:'iir in operating the device', hence I prefer to so connect the valves 15 and 23 that they may lo passes therethrough. 'A spring 17 resting upon the face of the oifset may' be uniformly maintained operate synchronously. To this end I secure an arm 2st upon the end of the valve stem 16 and connect the valve 23 thereto by a link or equivalent. means. It will thus be obvious that the operation ofthe hydro-carbon valve 15 involves the corresponding op-l eration/if the air valve. Suitable means are provided for the adjustment of the two valves relative/to one another. This may be readily accomplished in any preferred manner for example by adjusting the position of the arm 24 on the stem 16, the set screw serving to firmly maintain the parts -in their ad- 'justedpositions A handle 27 secured to the stem 16 serves as means for operating the valves. If desired the valves 15 and 23 -may be .disconnected and be independently operata-ble as showno in F ig. G, the construction previously described and clearly shown in Figs. 1, 2 and 3 is preferred however.-

Any preferred means may be employed to indicate the position of the valves. As shown in 1 a part ofthe periphery of the valve l5 is graduated, while a linger or pointer 2S fixed to the extension 13, vcoperating therewith seves this purpose.

, lVithin the. shell or mixing chamber means' are provided to secure a thorough commingling of the intlowing liquid and air. In the preferred construction shown a spreader or detlector is arrangeduto direct the current of air in contact with the hydro-carbon liowing in through the annular inlet 8. In the form n shown in Figs. 3 and 10, the base is formed semi-spherical or spheriforin, and a correspondingly formed spreader or detiecdtor 29 slightly smaller than the .interior in the base cooperates therewith in the operation of the device. That is to say, the exterior of they spreader is a spherical segment. In the preferred form shown in Fig. 3, the deliector is vertically movable normally resting in such a position as to tend to close the inlets 8 'and 9,and to prevent the inliow of both hydro-carbon and air. A

The operation of the engine or a coperating pump to which the device vis attached,

4 however, will tend to produce a. partial vacuum 'in the mixing chamber, momentarily lifting the detiector and providin a narrow channel between the exterior sur ace of the same and'tlfe interior of the shell. The same action permits the inflowing of the hydrocarbon through the annular inlet 8, and the air through the inlet 9, the current of air being directed over the ring of lluid hydrocarbon, taking up a quantity thereof and iilling the chamber with the mixture. As the delector 29 assumes its normal position it contacts with the ring of fluid tending to spread the saine out evenly into a thin film between and coating the surfaces of the proximate parts forming the channel between the detlecte'r and the chamber. This action obviously thinly spreads the liquid hydro-carbon out ovepn a comparatively large area. comprising` the exterior of the deiiector and the interior of the shell over which area the regulated .currentn of inflowing air is periodically and evenly directed at the pulsating operation ofthe device.

As shown in Figs. 3 and 9 a transverse plate 30 is positioned in the shell securing the end of a guide post 31 carried by the deiector, while a. spring 3Q positioned'between 75 a shoulder 33 on the post and the plate aids yin the accurate operation of the device.

Guiding extensions fr carried on the bottoni of the spreader and extending into the air inlet 9 supplement this action. Obviously 80 the spring may be dispensed-with and gravity alone belrelied upon to insure the operation of the deifiector. The detlector is preferably substantially closed at the top as at Z, to prevent the accumulation of liuid therein. In practice I have found the construction described very effective and the mixture satisfactory. I have however, shown auxiliary means to aid in securing a more thorough mixture, .which will be later referred to.

` In the form shown in Fig. 10, the de` Hector 29 is supported by the plate 30 in such amanne'ras to be permanently separated from the base and pulsating action thereof is dispensed with. This is obviously an inferior equivalent arrangement however, since the hydro-carbon is not mechanically spread over the exterior surface of the deiiector and the areaof the liquid film is reduced to that extent. In the form shown in Fig. 9 the 10o detiector 34 is'forin'ed with an exterior corresponding to the fiustum of' a cone, the inl terior of the base being correspondingly formed. Obviously the si'irfaces in this form are not as extensive as in the form shown in Fig. 3.

In the auxiliary mixing means vmentioned 'the plate 30, a plan of which is shown in Fig.

8 is a plate having its periphery formed with angular channels 35 through which the car- 110 bureted air is drawn, breaking it up into a plurality of currents. This may be suppleinented by vertical extensions 36 on the face' of the plate which serve as supports for a second plate 37 resting thereon. The exten- 115 sions are separated from one another and form openings for the carbureted air which passes 4through a central aperture 33 in the plate 37'and thence to the outlet 'and induction pipe 3f) which leads to the. engine, 120 pump, or other point-of delivery. In the form shown in Fig. 3, four such plates are shown. The several plates therefore act as batlles in which the current'is causedvto pass `around the periphery of a plate and throughv into a room or other adapted for use for sanitary purposes. Thus Yby using a liquid disinfectant or germicide and employing a suitable -pump vthe airacts as a vehicle and the mixture may be 'charged closed space or forced through fabrics or otherwise employed as desired.

Having thus described my im rovement it is obvious lthat immaterial modifications ma be made without departin' from the spirit of my invention, hence I o not wish to be understood as limiting myself to the precise form and construction shown. at I claim as new, and desire to secure by Letters Patent is kind described, a
